AgingContamination Task Group Status

1

• Aging/Contamination Task Group Status
• Discussed Contamination Survey Results
• Age of Airplane? Original intent was general
  survey to validate types of contamination to
  implement some controlled tested.
• Results are believed to align with Aging Wiring
  task group results. Will contact Aging Wiring
  group for data samples will be and photos of
  in-service locations of areas that accumulate
  dust/lint. Determine if testing was done with
  various levels of dust/lint/contamination.
• Revise survey form to be specific about
  locations. Consider a web-based survey form.
  Align this survey with request for general
  in-service blanket samples across the fleet.
  These blankets will define the as-is condition of
  blankets contamination level, thermal/analytical
  testing, and flammability properties. Results
  will be compared to lab tests on various levels
  of contamination types.

• Aging/Contamination Task Group Status
• Contamination Survey Results (continued)
• Generally agreed with the priority of
  contamination types dust/lint, CIC's, and
  fluids. CIC's will be easiest to start some
  controlled tests on different products. Boeing
  Airbus will define the list of CIC's and that
  have been used and define a proposed test plan to
  run some tests. Airlines will define what CIC
  products that have used.
• Dick Hill discussed some specific incidents that
  had very specific fire fuel sources isopropyl
  alcohol, etc illustrating that fluids and the
  processes used by airlines will be difficult to
  define common items.
• Airlines will initially identify the common
  cleaning solvents that are used during
  maintenance.

• Aging/Contamination Task Group Status
• Contamination Survey Results (continued)
• In the future need to look at other types of
  contamination such as insecticides and
  disinfectants (SARs).
• Quickest Completed Action Item Award
• Before the working meeting was over!

• Aging/Contamination Task Group Status
• Discussed In-service Blanket Sample Collection
• Agreed to have OEMs define very specific
  locations, Airlines identify heavy maintenance
  schedules 2 3 months in the future, so
  replacements blankets can be fabricated.
• Breif Discussion on next material/part types to
  evaluate
• from an aging/contamination effect.
• Align with Hidden Materials task group.
• Determine if a data driven approach can be
  used by reviewing in-service events and fire
  event participators.
